Use your iPad as a lightbox for tracing! I have created this simple app to transfer digitally created sketches to drawing paper - it runs on any iPad including the first generation (iOS 5.1.1).
Import a picture from your saved photos, or paste an image from the clipboard. Scale, position, and rotate (90 degree increments - use the toolbar button) to your taste.
With an additional in-app purchase, you can use filters to enhance the image for easier tracing. You can test drive this feature a few times for free.
If all you need is a big white light (for tracing from another piece of paper), press the white square on the toolbar instead.
Hit the "lock" icon to set the screen to maximum brightness and pin the picture down - subsequent touch events are ignored. You can now place a sheet of paper onto the display and trace the image, without accidentally moving it around.
Note: You also should disable the 4- and 5-finger multitasking gestures in the general section of your device settings.
To re-enable the user interface, deactivate the app with the device's home button, then activate it again.
New filter panel for enhancing the image used for tracing: brightness, saturation, contrast, and threshold. This is an in-app purchase, but you can try it out for free.
Also added a help page and fixed a few UI glitches.

Always sideways, but good locking function
Unless it's a screenshot or an image I saved in the net....
All photos I've taken myself are always sideways. Not even because I took the picture with my device sideways or anything. It just always puts it sideways and stretches the image to fit the screen. Making the "turn 90 degrees" and "scale" functions absolutely useless, because it's already distorted the image to fit the screen. All my upright photos are being turned sideways and stretched upwards.
If you want a Lightbox for images you download, I think it'll be worth it for the locking screen function. Otherwise, if you ever hope to use your own photos, you're better off finding something else.
Works and Locks Well
I think they must have fixed the image flipping issue, because my imported photos aren't distorted or flipping. I appreciate the small size of the file and that the lock file is easy to find/use. No issues here.
The only problem I have is now I need a 24 inch iPad Pro.
Works great as a Traditional Lightbox. I sometimes need to trace a drawing from one piece of paper to another. This app does it, and it locks the screen down so I don’t accidentally wipe the app away when drawing.
With Family Sharing set up, up to six family members can use this app.
